"In their place is a man humbled by the error of his ways, and one who is fixed upon paying his debt to society, in full, with interest," wrote Butner federal prison inmate John P. Karoly, describing fellow inmate and former Illinois U.S. Rep. Jesse Jackson Jr. in a letter obtained by AL.com.

Jackson pleaded guilty in February 2013 to using $750,000 in campaign funds to enrich himself and his wife.

AL.com previously reported that it received emails from Jackson earlier this month as well as Karoly's nine-page letter and an affidavit signed by Karoly and Jackson. The letter stated that Jackson wants President Barack Obama to issue presidential pardons to all ex-offenders who have served their time.

AL.com wrote a letter to Jackson inquiring about his ideas for prison reform after he was transferred from Butner in North Carolina to the federal prison at Maxwell Air Force Base in Montgomery, Alabama. Jackson pleaded guilty in February 2013 of using $750,000 in campaign money to enrich himself and his wife.

"While I have not granted an interview in nearly 6 years, I am inclined to be responsive to your request as your request appears to not center around me and my well documented legal problems, for which I accepted full responsibility in open court and before the American people," wrote Jackson in his emailed reply.

Jackson told AL.com he wrote two books while incarcerated, "The Tao of Jesus Christ," and "The Last Campaign: A Memoir." He said the work he did with inmates at Butner was important to his "social experiments with the truth regarding the system."

In the letter, Karoly wrote that Jackson "yearns for the forgiveness that eluded him," after embarrassing himself, his family name, and "all those that counted on him to be different."

According to Karoly's letter, the presidential pardons available to all ex-offenders under Jackson's plan would be identical to the one President Gerald Ford issued to former President Richard Milhaus Nixon in 1974.

"Jesse has said, if this language was good enough for Richard Milhaus Nixon, it is good enough for every American," Karoly wrote. "This is not your stereotypical political begunk."

Jackson also called on Obama to pardon the leaders of American slave rebellions, according to Karoly's letter.

"Jesse points out that President Gerald F. Ford pardoned Robert E. Lee, of all people, but not Nat Turner or Denmark Vesey," Karoly wrote. "President Obama would be the perfect executive to issue those pardons. And who, asks Jesse, would be against forgiving the dead?"

According to the Chicago Sun-Times, Jackson's family is concerned for his mental health. Jackson's brother, Jonathan, called the news reports detailing Jackson's plans "nonsensical, erratic stuff," and wondered if Jackson was off his medication.
